Unlocking the Accessibility of Alkyl Radicals from Boronic Acids through Solvent-Assisted Organophotoredox Activation

Boronic acids facilitate the transport of ribonucleosides through lipid bilayers.

Boronic acids were found to facilitate the transport of various ribonucleosides in and out of liposomes (artificial cells). Most experiments were conducted with large unilamellar vesicles composed of dipalmitoylphosphatidyl choline, cholesterol, and phosphatidic acid in the ratio 20:15:2. Rates of nucleoside efflux were determined by a UV assay, whereas the influx experiments used a radiotracer...

Microwave-assisted Synthesis of Nـ alkyl 2ـ ketomethyl quinoline Derivatives Under Solvent-free Conditions

A series of Nـ alkyl 2ـ ketomethylquinoline derivatives were synthesis by reaction of benzoyl chloride derivatives with Nـ methyl quinaldine iodide in the presence of triethyl amine under microwave irradiation. Enaminone form of the product study by spectroscopy method. The result revealed the  Nـ alkyl 2ـ ketomethylquinoline the fixed enaminone tautomer.

A practical electromediated ipso-hydroxylation of aryl and alkyl boronic acids under an air atmosphere.

An efficient electromediated aerobic ipso-hydroxylation reaction of aryl and alkyl boronic acids has been developed. Furthermore, mechanistic insight into the role of superoxide anions in this reaction has also been provided based on electrochemical studies and experimental results.
